Zusammenfassung:	The utility model relates to an efficient direct expansion liquid supply Freon air cooler return air collecting pipe which comprises a first return air collecting pipe, a first 90-degree connecting elbow, a second 90-degree connecting elbow, a third 90-degree connecting elbow, a fourth 90-degree connecting elbow and a return air connecting pipe which are connected in sequence. According to the efficient direct expansion liquid supply Freon air cooler return air collecting pipe, an oil return bend composed of a first 90-degree connecting bend, a second 90-degree connecting bend, a third 90-degree connecting bend and a fourth 90-degree connecting bend is arranged at the lower end of a first return air collecting pipe. According to one embodiment of the utility model, the oil return bend is arranged along the width direction of the fan, so that the boundary dimension of the air cooler can be reduced, and meanwhile, the problem of oil accumulation does not exist. Besides, the air return collecting pipe is designe
